Association of ultraprocessed food consumption with risk of rheumatoid arthritis: a retrospective cohort study in the UK Biobank

BackgroundLimited studies explored the association between consumption of ultraprocessed food (UPF) and rheumatoid arthritis (RA). ObjectivesThis study aimed to examine the association between UPF consumption and RA risk and explore the potential mediating effects of RA-related biomarkers. MethodsThis retrospective cohort study included 207,012 participants without RA at recruitment and completed 24-h dietary recalls. UPF was defined based on the NOVA food classification system. Incident RA was ascertained using the International Classification of Diseases version 10. Cox regression models were used to examine the association between UPF consumption and the incidence of RA. Additionally, mediation analyses were conducted to evaluate the contribution of biomarkers related to the lipid profile, systemic inflammatory factors, serum liver enzymes, and glucose metabolism to the observed associations. ResultsThe participants’ mean (standard deviation [SD]) age at recruitment was 56.08 (7.95) y. During a median follow-up of 12.24 (interquartile range: 11.66–13.03) y, 1869 RA events were recorded. Compared with the lowest quintile of UPF consumption (weight percentage of the UPF), the adjusted hazard ratio (HR) of RA in the highest quintile was 1.17 (95% confidence interval (CI): 1.01, 1.36). There was a 6% elevated risk of RA incidence per SD increase in UPF intake (HR: 1.06; 95% CI: 1.01, 1.11). In the mediation analyses, the biomarkers explained 3.07%–14.80% of the association between UPF intake and RA. ConclusionsHigher UPF consumption was associated with an increased risk of RA, which may be mediated by inflammation, lipids, and liver enzymes. Lower UPF consumption is recommended to reduce RA incidence.

Trends in nonsugar sweetener use among United States adults by chronic diseases presence: 1999 to March 2020

BackgroundAlthough long-term health effects of nonsugar sweeteners (NSSs) are uncertain, they are widely used as a common alternative to added sugar, especially among people with chronic diseases. It is essential to evaluate trends in NSS use to inform policy makers. ObjectivesThis study aimed to investigate trends in NSS use overall and by chronic diseases presence in United States adults. MethodsThe analysis used data of United States adults (≥20 y) collected in National Health and Nutrition Examination Survey [NHANES (1999 to March 2020)]. Age-adjusted percentage of individuals consuming NSS beverages, NSS foods, tabletop NSS, or any of them during the first 24-h dietary recall period was calculated in each NHANES survey cycle. Weighted multivariable logistic or linear regression models were used to examine trends in NSS use over time. ResultsA total of 51,703 United States adults were included in the analysis. In total population, age-adjusted percentage of individuals consuming NSS in the past day increased from 29.3% in 1999–2000 to 37.5% in 2005–2006 and decreased to 24.1% in 2017 to March 2020 (P < 0.001 for nonlinear trend). Similar trends were observed for different subcategories of NSS-containing product consumption (NSS beverages, foods, and tabletop sweeteners). Similar trends were found among individuals with or without chronic disease. Among individuals with ≥1 chronic disease (cancer, cardiovascular disease, diabetes, hypertension, obesity, hyperlipemia), age-adjusted percentage of individuals consuming NSS in the past day increased from 34.5% in 1999–2000 to 41.1% in 2005–2008 and decreased to 28.1% in 2017 to March 2020, while NSS consumption increased from 20.0% in 1999–2000 to 27.4% in 2005–2008 and decreased to 14.3% in 2017 to March 2020 among individuals without chronic diseases (all P < 0.001 for nonlinear trend). ConclusionsNSS use increased from 1999 to 2006 and decreased until March 2020 among entire United States adults and individuals with or without chronic diseases. Moreover, NSS use is generally higher among individuals with chronic diseases during study periods.

Association between dietary magnesium intake and incident chronic kidney disease: a prospective observational cohort study

BackgroundAlthough serum magnesium deficiency is linked to higher cardiovascular disease risk, its association with chronic kidney disease (CKD) remains unclear. ObjectivesThis study aimed to evaluate the relationship between dietary magnesium intake and CKD development in adults with clinically normal kidney function. MethodsThe prospective observational cohort study evaluated 188,510 participants (median age, 57.0 y; female, 54.1%) from the UK Biobank. Dietary magnesium intake was assessed through a 24-h dietary recall questionnaire compromising a list of 206 foods and 32 beverages and categorized into quintiles. The primary outcome was incident CKD diagnosed through International Classification of Diseases-10 and Office of Population Censuses and Surveys 4 codes. Incident CKD, defined as estimated glomerular filtration rate (eGFR) of <60 mL/min/1.73 m2, was also assessed in a subcohort with creatinine follow-up data. ResultsThe median magnesium intake amount per person was 323.2 mg/d [interquartile range (IQR): 269.4–382.7 mg/d]. During 1,826,038.1 person-years of follow-up (median: 9.6 y; IQR: 9.3–10.3 y), CKD developed in 5,878 participants. The incidence of CKD was progressively higher in participants with lower magnesium intake (2.8%, 2.8%, 3.0%, 3.2%, and 3.7% in Q5–Q1, respectively). Cox regression analysis revealed that the hazard ratios (HRs) for incident CKD increased in a stepwise manner toward lower magnesium intake quintiles {adjusted HR (95% confidence interval [CI])—Q4: 0.97 (0.89, 1.06); Q3: 1.05 (0.96, 1.14); Q2: 1.12 (1.03, 1.21); Q1: 1.30 (1.20, 1.41)} relative to Q5 (P-linearity < 0.001). Similar results were observed with eGFR-defined CKD outcome [adjusted HR (95% CI)—Q4: 1.09 (0.92, 1.28); Q3: 1.15 (0.98, 1.35); Q2: 1.21 (1.03, 1.42); Q1: 1.41 (1.20, 1.65) relative to Q5; P-linearity < 0.001]. ConclusionsLower dietary magnesium intake was associated with higher risk of incident CKD in adults with clinically normal kidney function. Further controlled studies are required to establish the potential benefit of adequate magnesium intake.

The Effect of Daily Avocado Intake on Food and Nutrient Displacement in a Free-Living Population with Abdominal Obesity

BackgroundAvocado intake has been associated with improvements in diet quality. Whether this response is because of avocado intake, per se, or combined with a food and/or nutrient displacement (D) has yet to be determined. ObjectivesThis secondary analysis, conducted using dietary data from the Habitual Diet and Avocado Trial, sought to assess the effect of consuming a large avocado (168 g, 281 kcal) daily in the avocado-supplemented diet (AD) group compared with the habitual diet (HD) group on food and nutrient D. MethodsUsing data from 3 unannounced telephone 24-h dietary recalls conducted during the 6-mo intervention period, food intake data were evaluated for 898 participants, aged 25–87 y, and a BMI range of 20.5–60.3 kg/m2. The food group distribution, energy, and nutrient intake of the AD group (n = 436) were calculated and compared with those of the HD group (n = 462). ResultsThe AD group had a higher daily intake of energy (159 ± 575 kcal) (P < 0.001), potassium (3193 ± 817 mg compared with 2419 ± 843 mg) (P < 0.005), fiber (30 ± 8 g compared with 19 ± 9 g) (P < 0.05), and a lower daily intake of animal protein (49 ± 33 g compared with 55 ± 24 g) (P = 0.02) compared with the HD group. Partial D with an avocado was observed for energy (43%), total fat (23%), and carbohydrate (87%), indicating a lower intake of these nutrients from non-avocado sources in the AD group. Food group analysis revealed a lower consumption of animal-derived protein from red meat, processed meats, poultry, and fish in the AD group, with no significant differences observed in dairy and egg intake between groups. ConclusionsIncorporating 1 avocado daily led to favorable modifications in the dietary composition of participants, including an increase in potassium and fiber intake, which can improve diet quality.This trial was registered at https://clinicaltrials.gov as NCT03528031.

Micronutrient deficiency, dietary diversity, and sociodemographic and lifestyle determinants of dietary diversity among pregnant slum-dwelling women in Pune, India

BackgroundIncreasing dietary diversity is a sustainable solution to combat micronutrient deficiencies. Given the large slum population in urban India, double burden of malnutrition, nutritional transition among slum-dwellers, and limited studies focusing on dietary intake and diversity among pregnant slum-dwellers, this study aimed to 1) describe macro- and micronutrient intakes and compare them with guidelines, 2) describe dietary diversity and intake of unhealthy foods and, 3) investigate the sociodemographic and lifestyle determinants of adequate dietary diversity among pregnant slum-dwellers in Pune, Maharashtra, India.MethodsThis study presents cross-sectional data of 454 pregnant slum-dwelling women completing mid-pregnancy visit collected from a larger cohort study. Sociodemographic and lifestyle data were collected at baseline (< 12 weeks gestation). Dietary data (24-h dietary recall) were collected in mid-pregnancy (23 ± 2 weeks). Nutrient intakes were compared with the Estimated Average Requirements (EAR) for pregnant Indian women. Dietary diversity score (DDS, range 0–10) and unhealthy food (sweet snacks, sweet beverages, fried and salty food) group score (range 0–3) were calculated as per FAO guidelines. Multivariate logistic regression was conducted to examine determinants of adequate dietary diversity (DDS ≥ 5).ResultsThe average age of women was 25 (4.5) years. The median (Q1, Q3) total energy and protein intakes were 1771 (1456, 2185) kcal/d and 44.7 (34.7, 55.0) g/d, respectively. Total energy and protein were consumed as per EAR by 37% and 54% of women, respectively. Forty percent of women exceeded the recommended energy intake from carbohydrates. Diets of slum-dwelling women were lacking in multiple micronutrients (especially iron, zinc, riboflavin, thiamine, folate). The mean DDS was 4.2 ± 1.2 and 36.5% of the women had DDS ≥ 5. All women consumed mainly cereal-based starchy staples; 80% consumed pulses and legumes, and 60% consumed other vegetables. Fifty-nine percent of women consumed ≥ 2 unhealthy food groups. Higher educational and occupational status of the primary earning members of the family and lower parity were determinants of adequate dietary diversity.ConclusionThe diets of pregnant slum-dwelling women were lacking in numerous micronutrients. Dietary counselling programs need to be tailored to the socioeconomic backgrounds of pregnant slum-dwelling women and involve their family members to improve reach and effectiveness.

Dietary intake of luteolin is negatively associated with all-cause and cardiovascular mortality in chronic kidney disease patients

BackgroundLuteolin (Lut), a flavonoid present in the daily diet, exhibits potent anti-inflammatory and renoprotective effects. However, the association between Lut and chronic kidney disease (CKD) remains uncertain. The objective of this study is to explore the potential correlation.MethodsA total of 2,393 CKD patients were enrolled in a prospective cohort in the National Health and Nutrition Examination Survey (NHANES). A 24-h dietary recall was utilized to estimate the intake of dietary Lut based on the type and amount of food consumed. The National Death Index mortality data was utilized to ascertain all-cause and cardiac mortality (as of December 27, 2023). Cox proportional hazards model was used to estimate the relationship between Lut intake and mortality risk.ResultsThe median Lut intake was 0.305 mg/day, with interquartile range was 0.105–0.775 mg/day. During the follow-up period (median, 93 months), 682 all-cause deaths (217 cardiovascular disease [CVD] deaths) were recorded. Per unit increase in Lut intake reduced all-cause mortality by 27% (P < 0.001) and cardiac mortality by 34% (P = 0.01) in CKD patients. There was an inverse dose–response association between Lut intake (range: 0–8.945 mg/day) and mortality risk. Consistent results were also shown when stratified by age, sex, race, marital status, body mass index, CKD stage, urine protein creatinine ratio strata, CKD progression risk, hypertension, and CVD.ConclusionDietary Lut intake is associated with a reduction in all-cause and cardiac mortality among CKD patients, potentially attributable to the anti-inflammatory characteristics of Lut.

Are dietary factors associated with cardiometabolic risk factors in patients with non-alcoholic fatty liver disease?

Non-alcoholic fatty liver disease (NAFLD) is intricately linked with dietary patterns and metabolic homeostasis. Therefore, the present study focused to investigate the relation between dietary patterns and cardiometabolic risk factors related to fatty liver in NAFLD patients. This cross-sectional study included 117 individuals whose body mass index (BMI) threshold of 25 or above diagnosed with NAFLD by magnetic resonance imaging. The hospital database was used to review the patients' medical records such as lipid parameters, and fasting blood sugar. Anthropometric measurements and body composition were measured by researchers. Likewise, data from 24-h dietary recalls of individuals were collected to analyze their energy and nutrient intakes besides calculating dietary insulin index (DII), dietary insulin load (DIL), dietary glycemic index (DGI), and dietary glycemic load (DGL). Participants consuming diets with distinct levels of DII, DIL, DGI, and DGL exhibited variations in dietary energy and nutrient intake. Specifically, differences were noted in carbohydrate intake across quartiles of DII, DIL, DGI, and DGL, while fructose consumption showed variability in DGL quartiles (p ≤ 0.05). Moreover, sucrose intake demonstrated distinctions in both DII and DGL quartiles (p ≤ 0.05). No statistical difference was found in biochemical parameters and the fatty liver index among different levels of DII, DIL, DGI, and DGL (p > 0.05). After adjusting for potential confounders, participants with a higher DGI had four times greater odds of developing metabolic syndrome compared to those in the bottom quartile (OR, 4.32; 95% CI [1.42-13.11]). This study provides initial evidence of the intricate association between dietary factors and NAFLD, emphasizing the necessity for further research including prospective designs with larger sample sizes, to garner additional insights.

Biomarker panels for fruit intake assessment: a metabolomics analysis in the ELSA-Brasil study.

Food intake biomarkers are used to estimate dietary exposure; however, selecting a single biomarker to evaluate a specific dietary component is difficult due to the overlap of diverse compounds from different foods. Therefore, combining two or more biomarkers can increase the sensitivity and specificity of food intake estimates. This study aimed to evaluate the ability of metabolite panels to distinguish between self-reported fruit consumers and non-consumers among participants in the Longitudinal Study of Adult Health. A total of 93 healthy adults of both sexes were selected from the Longitudinal Study of Adult Health. A 24-h dietary recall was obtained using the computer-assisted 24-h food recall GloboDiet software, and 24-h urine samples were collected from each participant. Metabolites were identified in urine using liquid chromatography coupled with high-resolution mass spectrometry by comparing their exact mass and fragmentation patterns using free-access databases. Multivariate receiver operating characteristic curve (ROC) analysis and partial least squares discriminant analysis were used to verify the ability of the metabolite combination to classify daily and non-daily fruit consumers. Fruit intake was identified using a 24h dietary recall (24h-DR). Bananas, grapes, and oranges are included in the summary. The panel of biomarkers exhibited an area under the curve (AUC) > 0.6 (Orange AUC = 0.665; Grape AUC = 0.622; Bananas AUC = 0.602; All fruits AUC = 0.679; Citrus AUC = 0.693) and variable importance projection score > 1.0, and these were useful for assessing the sensitivity and predictability of food intake in our population. A panel of metabolites was able to classify self-reported fruit consumers with strong predictive power and high specificity and sensitivity values except for banana and total fruit intake.

Evaluation of daily eating patterns on overall diet quality using decision tree analyses

BackgroundPreliminary evidence suggests that meal timing is associated with higher quality diets. Less is known about whether types of food consumed during specific eating episodes (i.e., day-level eating patterns) predict diet quality. ObjectivesWe investigated the association between day-level eating patterns and diet quality. MethodsDecision tree models were built using 24-h dietary recall data from the National Health and Nutrition Examination Survey 2015 and 2017 cycles in a cross-sectional study. Sixteen food groups and 12 eating episodes (e.g., breakfast, lunch) were included as input parameters. Diet quality was scored using the Healthy Eating Index-2020 and categorized as higher or lower quality diets based on the median score. Mean decrease in impurity (MDI) ± standard deviation determined the relative contribution that day-level eating patterns had on diet quality; higher values represented greater contributions. ResultsWe analyzed 12,597 dietary recalls from 9347 United States adults who were aged 18 y and older with ≥1 complete recall. Meals (breakfast, lunch, dinner) and respective snacking episodes had the greatest variety of dietary groups that contributed to the Healthy Eating Index-2020 score. Any whole-grain intake at breakfast predicted a higher quality diet (MDI = 0.08 ± 0.00), followed by lower solid fat intake (<8.94 g; MDI = 0.07 ± 0.00) and any plant protein intake at dinner (MDI = 0.05 ± 0.00). ConclusionsDay-level eating patterns were associated with diet quality, emphasizing the relevance of both food type and timing in relation to a high-quality diet. Future interventions should investigate the potential impact of targeting food type and timing to improve diet quality.

Association of ultraprocessed food consumption with risk of microvascular complications among individuals with type 2 diabetes in the UK Biobank: a prospective cohort study

BackgroundThe poor nutritional characteristics and potentially harmful molecules in ultraprocessed foods (UPFs) are risk factors for diabetic microvascular complications. However, the evidence regarding UPFs and diabetic microvascular complications remains limited. ObjectivesWe aimed to evaluate the associations between UPF consumption and risk of diabetic microvascular complications, to examine the underlying biological pathways (e.g., inflammation and lipid profile), and to identify whether the associations differ by type of UPF dietary patterns. MethodsWe included a prospective cohort of UK Biobank participants with type 2 diabetes (T2D) having at least one 24-h dietary recall (N = 5685). UPFs were defined using the Nova classification. Principal component analysis was used to derive UPF consumption patterns. Associations of UPFs and their consumption patterns with microvascular complications were assessed using Cox proportional hazards regression models. Mediation analyses were used to estimate the mediating effects of 22 biomarkers. ResultsDuring a median of 12.7 y of follow-up, 1243 composite microvascular complications events occurred (599 diabetic retinopathy, 237 diabetic neuropathy, and 662 diabetic kidney disease events). Five consumption patterns were identified (spread and bread, cereal prepared with liquids, dairy-based products, sugary beverage and snack, and mixed beverage and savory snack patterns). A 10% increment in the proportion of UPF was associated with higher hazards of the composite microvascular complications (hazard ratio [HR]: 1.08; 95% confidence interval [CI]: 1.03, 1.13) and diabetic kidney disease (HR: 1.13; 95% CI: 1.06, 1.20). Triglycerides, C-reactive protein, and body mass index collectively explained 22.0% (9.6%–43.0%) of the association between UPF intake and composite microvascular complications. Pattern high in mixed beverage and savory snack was associated with a higher risk of composite microvascular complications. ConclusionsHigher UPF consumption was associated with higher risks of diabetic microvascular complications, and the association was partly mediated through multiple potential ways.

Association between dietary inflammatory index and energy-adjusted dietary inflammatory index and constipation in US adults

BackgroundDiet and inflammation are associated with constipation. Dietary inflammation index (DII) and energy-dietary inflammation index (E-DII) have not been evaluated together with constipation. Therefore, this study was conducted to further observe the relationship between DII and E-DII and constipation in American adults.MethodsData were extracted from the National Health and Nutrition Examination Survey (NHANES) for 12,400 adults aged 20 years and older between 2005 and 2010. DII and E-DII were obtained by employing data from the two 24-h dietary recall of the participants. Constipation was defined and categorized using the Bristol Stool Form Scale.ResultsIn the logistic regression model, the relationship between DII and E-DII and constipation remained positive after adjusting for confounding factors (odds ratio [OR] = 1.13; 95% confidence interval [CI]: 1.07–1.20 in DII logistic regression model III; odds ratio [OR] = 1.09; 95% confidence interval [CI]: 1.03–1.17 in E-DII logistic regression model III). Constipation was more common in quartile 4 (DII: 2.87—5.09; E-DII: 1.78—8.95) than in quartile 1 (DII: -5.11—0.25; E-DII: -2.60—0.11) (OR = 1.79, 95% CI: 1.30–2.47 in DII and OR = 1.75, 95% CI: 1.25–2.46 in E-DII for all participants; OR = 2.04, 95% CI: 1.39–3.00 in DII OR = 2.20, 95% CI: 1.39–3.47 in E-DII for males; OR = 1.86, 95% CI: 1.08–3.22 and OR = 1.80, 95% CI: 1.06–3.06 for females). These results were confirmed using multiple imputations.ConclusionsThe findings of this study show that a high DII and E-DII were associated with an increased incidence of constipation among US adults.

Intake of dietary flavonoids in relation to overactive bladder among U.S. adults: a nutritional strategy for improving urinary health.

The increasing influence of overactive bladder (OAB) on physical as well as mental health of individuals is becoming more pronounced annually, as evidenced by the urge urinary incontinence and nocturia. Symptoms in OAB patients may be influenced by inflammation and oxidative stress. Flavonoids are recognized as significant anti-inflammatory and antioxidant agents, which are commonly available in fruits, tea, vegetables, etc. Previous research has demonstrated the therapeutic potential of flavonoids and their subclasses in treating inflammation, and oxidative stress. Despite this, there remains a paucity of research exploring the potential correlation between flavonoid consumption, specifically within distinct subclasses, and OAB. Thus, our study aims to investigate the relationship between flavonoid intake and OAB to identify possible dietary interventions for OAB management. We utilized the survey data from the National Health and Nutrition Examination Survey (NHANES) and the USDA Food and Nutrient Database for Dietary Studies (FNDDS) to investigate the relationship between dietary intake of total and subclass flavonoids and the risk of OAB based on 13,063 qualified American adults. The dietary flavonoid intake was estimated from two 24-h dietary recalls. Weighted multivariate logistic regression model, quantile-based g-computation, restricted cubic spline model, and stratified analysis were used to explore the association between flavonoid intake and OAB, respectively. The participants diagnosed with OAB exhibited a higher percentage of being female, older, Non-Hispanic Black, unmarried, former drinkers, having a lower annual household income, lower poverty to income ratio, lower educational attainment, and a higher likelihood of being obese and smokers. Upon adjusting for confounding factors, the weighted logistic regression models revealed that the third quartile of consumption of anthocyanidin and the second quartile of consumption of flavone were significantly associated with the reduced odds of OAB, while total flavonoid consumption did not show a significant correlation with the risk of OAB. The quantile-based g-computation model indicated that flavone, anthocyanidin and flavonol were the primary contributors to the observed negative correlation. Furthermore, the restricted cubic spline models demonstrated a J-shaped non-linear exposure-response association between anthocyanidin intake and the risk of OAB (P nonlinear = 0.00164). The stratified and interaction analyses revealed that the relationship between anthocyanidin intake and the risk of OAB was significantly influenced by age (P interaction = 0.01) and education level (P interaction = 0.01), while the relationship between flavone intake and the risk of OAB was found to vary by race (P interaction = 0.02) and duration of physical activity (P interaction = 0.05). Our research suggests that consuming a diet rich in flavonoid subclass anthocyanidin and flavone is associated with a reduced risk of OAB, potentially offering clinical significance in the prevention of OAB development. This underscores the importance of dietary adjustments in the management of OAB symptoms.

Socioeconomic Inequalities in Intakes of Ultraprocessed and Minimally Processed Foods in Nationally Representative Samples of Adults in Canada: An Analysis of Trends between 2004 and 2015

BackgroundIndividuals with a lower socioeconomic position (SEP) often have higher intakes of ultraprocessed food (UPF) and lower intakes of minimally processed food (MPF); however, studies have not examined trends in absolute and relative gaps and gradients in UPF and MPF intake using multiple indicators of SEP. ObjectivesWe examined within-year absolute and relative gaps and gradients in UPF and MPF intake and trends between 2004 and 2015 according to 6 indicators of SEP among nationally representative samples of adults in Canada. MethodsAdults (≥18 y) in the Canadian Community Health Survey-Nutrition 2004 (n = 20,880) or 2015 (n = 13,970) reported SEP (individual and household education, household income adequacy, household food insecurity, neighborhood material and social deprivation) and completed a 24-h dietary recall. Multivariable linear regression assessed within-year absolute and relative gaps and gradients in the proportion of energy from UPF and MPF and trends between 2004 and 2015. ResultsThe largest and most consistent within-year inequities in UPF and MPF intake were for individual and household educational attainment. Overall and among males, higher SEP groups had more favorable intakes over time based on trends in absolute and relative gaps and gradients in UPF and MPF intake by household food insecurity [for example, the absolute gap in UPF intake declined from −1.2% (95% confidence interval: −5.3%, 2.9%) to −7.9% of energy (95% confidence interval: −11.2%, −4.5%) in the overall population]. Overall and among males, lower SEP groups had more favorable intakes over time based on trends in absolute and relative gaps in UPF and MPF intake by neighborhood material deprivation. ConclusionsSocioeconomic inequalities in UPF and MPF intake were most pronounced for individual and household education. Between 2004 and 2015, several inequalities in UPF and MPF intake emerged according to household food insecurity (favoring higher SEP groups) and neighborhood material deprivation (favoring lower SEP groups).

Association between dietary inflammatory index and all-cause mortality in patients with osteopenia or osteoporosis: A retrospective cohort study from the NHANES 2007–2018

ObjectiveOsteoporosis is an inflammatory disease that causes a large disease burden worldwide. Dietary inflammation index (DII), a comprehensive assessment index that reflects the pro-inflammatory/anti-inflammatory level of diet was related to multiple inflammatory diseases. This study aimed to explore the association between DII and all-cause mortality in patients with osteoporosis or osteopenia. MethodsIn this retrospective cohort study, data of patients aged ≥ 45 years diagnosed as osteopenia or osteoporosis and had complete dietary intake information were extracted from the National Health and Nutrition Examination Survey (NHANES 2007–2010, 2013–2014, 2017–2018). Dietary intake information was obtained from 24-h dietary recall interviews and was used to calculate the DII score. Weighted univariate and multivariate Cox proportional hazard models were utilized to explore the association between DII and all-cause mortality in patients with osteoporosis or osteopenia, with hazard ratios (HRs) and 95 % confidence intervals (CIs). Subgroup analyses based on different age, gender and complications were further assessed this association. ResultsA total of 5,381 patients were included. Until December 31, 2019, 1,286 all-cause deaths occurred. After adjusting all covariates, high DII was associated with the high odds of all-cause mortality among patients with osteoporosis or osteopenia (HR=1.28, 95 %CI: 1.10–1.48), especially in the male (HR=1.38, 95 %CI: 1.06–1.78), aged < 65 years (HR=1.49, 95 %CI: 1.09–2.02), and without the history the cardiovascular disease (HR=1.30, 95 %CI: 1.03–1.65), diabetes mellitus (HR=1.27, 95 %CI: 1.06–1.52) and chronic kidney disease (HR=1.28, 95 %CI: 1.03–1.58). ConclusionA pro-inflammatory diet may have an adverse effect on the prognosis of osteoporosis patients.

Association between dietary vitamin A intake and risk of cardiometabolic multimorbidity

The association between vitamin A and single cardiometabolic diseases has been extensively studied, but the relationship between dietary vitamin A intake and the risk of cardiometabolic multimorbidity (CMM) has not been studied. Therefore, the present study was conducted to explore the association with CMM risk by analyzing different sources of vitamin A. This study utilized 13,603 subjects aged ≥ 18 years from 1997 to 2015 from the China Health and Nutrition Survey (CHNS). Dietary intake was calculated from 3 consecutive 24-h dietary recalls combined with a house hold food inventory. CMM is defined as the development of at least two cardiometabolic diseases. After a median follow-up of 9.0 years, there were 1050 new cases of CMM. The risk of CMM was significantly lower in those with higher vitamin A intake (Q1 vs Q5 HR 0.66, 95% CI 0.54–0.81). β-carotene (Q1 vs Q5 HR 0.82, 95% CI 0.66–1.02) and retinol (Q1 vs Q5 HR 0.59, 95% CI 0.48–0.73) intake had a similarly negative correlation. Using restricted cubic spline found an L-shaped relationship between retinol intake and CMM (p non-linear < 0.001). Negative associations were also found in specific CMD groups (hypertension, cardiovascular disease, stroke and diabetes). Dietary intake of vitamin A was negatively associated with CMM risk, and this protective effect was more pronounced in patients with cardiovascular disease. There was an L-shaped association between retinol intake and CMM risk.

Estimated reduction in obesity prevalence and costs of a 20% and 30% ad valorem excise tax to sugar-sweetened beverages in Brazil: A modeling study.

The consumption of sugar-sweetened beverages (SSBs) is associated with obesity, metabolic diseases, and incremental healthcare costs. Given their health consequences, the World Health Organization (WHO) recommended that countries implement taxes on SSB. Over the last 10 years, obesity prevalence has almost doubled in Brazil, yet, in 2016, the Brazilian government cut the existing federal SSB taxes to their current 4%. Since 2022, a bill to impose a 20% tax on SSB has been under discussion in the Brazilian Senate. To simulate the potential impact of increasing taxes on SSB in Brazil, we aimed to estimate the price-elasticity of SSB and the potential impact of a new 20% or 30% excise SSB tax on consumption, obesity prevalence, and cost savings. Using household purchases data from the Brazilian Household Budget Survey (POF) from 2017/2018, we estimated constant elasticity regressions. We used a log-log specification by income level for all beverage categories: (1) sugar-sweetened beverages; (2) alcoholic beverages; (3) unsweetened beverages; and (4) low-calorie or artificially sweetened beverages. We estimated the adult nationwide baseline intake for each beverage category using 24-h dietary recall data collected in 2017/2018. Taking group one as the taxed beverages, we applied the price and cross-price elasticities to the baseline intake data, we obtained changes in caloric intake. The caloric reduction was introduced into an individual dynamic model to estimate changes in weight and obesity prevalence. No benefits on cost savings were modeled during the first 3 years of intervention to account for the time lag in obesity cases to reduce costs. We multiplied the reduction in obesity cases during 7 years by the obesity costs per capita to predict the costs savings attributable to the sweetened beverage tax. SSB price elasticities were higher among the lowest tertile of income (-1.24) than in the highest income tertile (-1.13), and cross-price elasticities suggest SSB were weakly substituted by milk, water, and 100% fruit juices. We estimated a caloric change of -17.3 kcal/day/person under a 20% excise tax and -25.9 kcal/day/person under a 30% tax. Ten years after implementation, a 20% tax is expected to reduce obesity prevalence by 6.7%; 9.1% for a 30% tax. These reductions translate into a -2.8 million and -3.8 million obesity cases for a 20% and 30% tax, respectively, and a reduction of $US 13.3 billion and $US 17.9 billion in obesity costs over 10 years for a 20% and 30% tax, respectively. Study limitations include using a quantile distribution method to adjust self-reported baseline weight and height, which could be insufficient to correct for reporting bias; also, weight, height, and physical activity were assumed to be steady over time. Adding a 20% to 30% excise tax on top of Brazil's current federal tax could help to reduce the consumption of ultra-processed beverages, empty calories, and body weight while avoiding large health-related costs. Given the recent cuts to SSB taxes in Brazil, a program to revise and implement excise taxes could prove beneficial for the Brazilian population.

A Comprehensive Investigation of Dietary Micronutrient Intakes and Risk of Alcoholic Liver Disease

BackgroundThe investigation of dietary micronutrient intakes and risk of alcoholic liver disease (ALD) based on observational studies was limited. ObjectivesOur study aimed to explore the associations of 30 dietary micronutrients intakes with risk of ALD, interactions between dietary micronutrients and genetic variation, and mediation effects of blood and urinary biomarkers on the associations between dietary micronutrients and risk of ALD. MethodsA case-control study was conducted within the UK Biobank cohort, with 231 incident ALD cases and 1386 controls. Dietary data were collected using a dietary questionnaire that relied on a 24-h dietary recall of the previous day. Logistic regression models were employed to assess the associations of dietary micronutrient intakes with risk of ALD. We conducted stratified analyses on the associations between dietary micronutrient intakes and risk of ALD by PNPLA3 rs738409 and tested the interactions between dietary micronutrients and genetic variation. In addition, we conducted mediation analyses to investigate the mediating effects of biomarkers on the associations between dietary micronutrients and risk of ALD. ResultsOur findings indicated significant inverse associations of thiamin, riboflavin, niacin equivalent, pantothenic acid, vitamin B-6, folate, vitamin E, calcium, magnesium, phosphorus, potassium, copper, iodine, and manganese with risk of ALD (all false discovery rate-Ptrend < 0.050). We also found a significant interaction between PNPLA3 rs738409 and magnesium (Pinteraction = 0.028). Creatinine (enzymatic) in urine, aspartate aminotransferase, and insulin-like growth factor 1 were the top 3 biomarkers with the highest number of significant mediation effects on the associations between the dietary micronutrients and risk of ALD. ConclusionsDietary intakes of thiamin, riboflavin, niacin equivalent, pantothenic acid, vitamin B-6, folate, vitamin E, calcium, magnesium, phosphorus, potassium, copper, iodine, and manganese were inversely associated with risk of ALD.

Association between vitamin B1 intake and hyperuricemia in adults

Studies investigating the relationship between dietary vitamin B1 intake and risk of Hyperuricemia (HU) are scarce, the present study aimed to examine the association of dietary vitamin B1 intake and HU among adults. This cross-sectional study included 5750 adults whose data derived from National Health and Nutrition Examination Survey (NHANES) from March 2017 to March 2020. The dietary intake of vitamin B1 was assessed using 24-h dietary recall interviews. The characteristics of study participants were grouped into five levels according to the levels of vitamin B1 quintile. Multivariate logistic regression analysis was used to estimate the odds ratio (OR) and 95% confidence interval (CI) of HU, according to the vitamin B1 intake quintile for male and female separately. The dose–response relationship was determined by the restricted cubic spline (RCS). Smoothed curve fitting was used to assess serum uric acid concentration versus dietary vitamin B1 intake in the study population. The prevalence of hyperuricemia was 18.90% (20.15% and 17.79% for males and females, respectively) in the United States from March 2017 to March 2020. Multiple logistic regression analyses showed that in the male population, the HU ratio (OR) of vitamin B1 intake in Q2 to Q5 compared with the lowest quintile (Q1) was 0.75 (95% CI 0.52, 1.09), 0.70 (95% CI 0.48, 1.02), 0.66 (95% CI 0.44, 0.99) and 0.55 (95% CI 0.34, 0.90). The P for trend was 0.028. In women, the ORs for vitamin B1 intake Q2 to Q5 were 0.87 (95% CI 0.64, 1.19), 0.97 (0.68–1.38), 1.05 (0.69–1.60) and 0.75 (0.42–1.34), respectively. The P for trend was 0.876. The RCS curve revealed a linear relationship between vitamin B1 intake and the risk of hyperuricemia in men (P nonlinear = 0.401). Smoothed curve fitting demonstrated a negative association between vitamin B1 intake and serum uric acid concentration in men, whereas there was no significant association between dietary vitamin B1 intake and the risk of hyperuricemia in women. In the US adult population, dietary vitamin B1 intake was negatively associated with hyperuricemia in males.

Associations Between Dietary Intake of Tomato and Lycopene with All-Cause and Cancer-Specific Mortality in US Adults with Diabetes: Results From a Cohort Study

This study aimed to explore the association between dietary intake of tomatoes and lycopene with all-cause and cancer mortality among US adults with diabetes. We hypothesized that a higher intake of tomato and lycopene is related to a reduced risk of all-cause and cancer mortality among adults with diabetes. This prospective study was conducted among 9213 US adults with diabetes using data from the National Health and Nutrition Examination Survey (NHANES) 2007–2016. Data on dietary intake of tomatoes and lycopene were obtained from two 24-h dietary recalls. Multivariate Cox proportional hazard models determined the associations between tomato/lycopene intake and mortality. A higher intake of tomatoes and lycopene was significantly associated with a lower risk of all-cause mortality (tomato: Q5 vs. Q1: HR = 0.68, 95% CI = 0.54–0.86, p = 0.001, p for trend = 0.001; lycopene: Q5 vs. Q1: HR = 0.78, 95% CI = 0.64–0.95, p = 0.013, p for trend = 0.006) after adjusting for all covariates. Compared with the lowest quintile of tomato and lycopene intake, the highest quintile was associated with a lower risk of cancer mortality (tomato: HR = 0.58, 95% CI = 0.35–0.96, p = 0.035; lycopene: HR = 0.63, 95% CI = 0.40–0.98, p = 0.043). Our study demonstrated that dietary intake of tomatoes and lycopene was significantly associated with a lower risk of all-cause mortality in US adults with diabetes. High consumption of tomatoes and lycopene was also related to reduced cancer mortality in US adults with diabetes.

Association between composite dietary antioxidant index and hyperlipidemia: a cross-sectional study from NHANES (2005–2020)

The association between the composite dietary antioxidant index (CDAI) and hyperlipidemia remains unclear. Therefore, this study aimed to investigate the relationship between CDAI and hyperlipidemia. The data used in this study were obtained from the National Health and Nutrition Examination Survey (NHANES) dataset spanning from 2005 to 2020. Based on 24-h dietary recall interviews, the CDAI was calculated using the intake of six dietary antioxidants. Univariate and multivariate logistic regression models were employed to investigate the relationship between CDAI and the occurrence of hyperlipidemia. Additionally, restricted cubic spline (RCS) analysis was utilized to investigate potential non-linear relationships between the CDAI and risk of hyperlipidemia. The final analysis included 30,788 adults in the United States, among whom 25,525 (82.91%) were diagnosed with hyperlipidemia. A significant negative correlation was observed between the CDAI and hyperlipidemia in the unadjusted (Odds ratio [OR] 0.97 [95% CI 0.96, 0.98]) and multi-variable adjusted (OR 0.98 [95% CI 0.97, 0.99]) models. When the CDAI values were analyzed as a categorical variable, individuals in the highest quartile (OR 0.82 [95% CI 0.73, 0.92]) exhibited a nearly one fifth decreased risk of hyperlipidemia compared to those in the lowest quartile. Additionally, RCS analysis revealed a linear relationship between CDAI and hyperlipidemia (P for nonlinearity = 0.124). The results remained consistent across subgroups except for individuals under the age of 60 or those with diabetes mellitus. There was a significant negative correlation between the CDAI and risk of hyperlipidemia, indicating that maintaining an optimal CDAI level could effectively reduce the incidence of hyperlipidemia.
